HARD FERRITE MAGNETSHard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.Ferrite Magnets characteristicsMostly Used national standard - SJ285-77 permanent ferrite magnet standardChinese SJ/T0410-2000 Permanent Ferrite Manget StandardIn MMPA（0100-87) standardRing shape size(mm) D×d×HФ115×45×5～23 Ф200×86×5～27 Ф70×32×3～17 Ф115×43×5～23 Ф200×83×5～27 Ф70×30.5×3～17 Ф115×45×5～23 Ф200×86×5～27 Ф70×32×3～17 Ф115×57×5～23 Ф200×95×5～27 Ф70×56×3～17 Ф115×58.7×3～23Ф200×100×5～27 Ф70×40×3～17 （elliptical）Ф115×60×5～23 Ф200×110×5～27 Ф71×40×3～17 Ф115×67×5～23 Ф200×120×5～27 Ф71×30.5×3～17 Ф115×80×5～23 Ф206×88.9×5～30 Ф71×32×3～17 Ф121×45×5～24 Ф206×89×5～30 Ф72×30.5×3～16 Ф121×57×5～24 Ф206×118×5～30 Ф72×32×3～16 Ф121×60×5～24 Ф210×86×5～30 Ф72×38×3～16 Ф121×65×5～24 Ф210×118×5～30 Ф72×40×3～16NdFeBKnown as third generation of Rare Earth magnets, Neodymium Iron Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnet today. Since they are made from Neodymium, one of the most plentiful rare earth elements, and inexpensive iron, NdFeB magnets offer the best value in cost and performance.NdFeB magnets are available in both sintered and bonded forms. Sintered NdFeB offers the highest magnetic properties (28 MGOe to 50 MGOe) while Bonded NdFeB offers lower energy properties. Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets, they can be made in shapes and sizes that are difficult to achieve with sintering.A variety of coatings can be applied to the magnets' surface to overcome the principle drawback of neodymium-based magnets, their tendency to corrode easily.Grade Max.

高频磁芯功率与频率对照表
高频磁芯功率与频率对照表摘要：一、引言二、高频磁芯的定义和分类三、磁芯形状、材料、绕组匝数与功率、电流、频率的关系四、常用磁芯与应用功率对照表五、磁芯的选用原则六、结论正文：一、引言高频磁芯是一种应用于高频电路中的磁性元件，主要用于变压器、扼流圈等电子设备中。
它的主要作用是在高频电路中传递能量，同时对电路的信号进行处理。
根据不同的应用场景，高频磁芯可以分为多种类型，如主功率变压器、驱动变压器、平滑扼流圈、辅助功率变压器等。
本文将对高频磁芯的功率与频率对照表进行探讨，并介绍磁芯的选用原则。
二、高频磁芯的定义和分类高频磁芯是一种具有良好磁性能和高频响应特性的磁性材料。
根据磁芯的形状、材料和应用场景，可以将高频磁芯分为不同的类型。
常见的高频磁芯有EE 型、EEL 型、ER 型等。
这些磁芯具有不同的特点，如引线空间大、绕制接线方便、适用范围广、工作频率高、工作电压范围宽、输出功率大、热稳定性能好等。
三、磁芯形状、材料、绕组匝数与功率、电流、频率的关系1.磁芯形状：磁芯的形状决定了其磁性能和绕制方式。
不同形状的磁芯适用于不同的电路和应用场景。
如EE 型磁芯适用于主功率变压器，EEL 型磁芯适用于驱动变压器，ER 型磁芯适用于平滑扼流圈等。
2.磁芯材料：磁芯材料决定了磁芯的工作频率和磁性能。
常见的高频磁芯材料有铁氧体、镍锌铁氧体、锰锌铁氧体等。
不同材料的磁芯具有不同的工作频率范围和磁性能，需要根据实际应用场景选择合适的磁芯材料。
3.绕组匝数：绕组匝数决定了磁芯的电感量和输出功率。
一般来说，绕组匝数越多，电感量越大，输出功率也越大。
但是，绕组匝数的增加也会导致磁芯的热损耗增加，影响磁芯的热稳定性能。
因此，需要根据实际应用场景和工作条件选择合适的绕组匝数。
四、常用磁芯与应用功率对照表以下是一些常用的高频磁芯及其应用功率对照表：1.EE 型磁芯：主要用于主功率变压器，适用功率范围为10-1000W。
2.EEL 型磁芯：主要用于驱动变压器，适用功率范围为10-500W。

GENERAL INFORMATION
The terms “Medium Voltage”and “high voltage”have been used interchangeably by many people to describe fuses operating above 600 volts.T echnically speaking, “medium voltage”fuses are those intended for the voltage range from 2,400 to 38,000 VAC.“High voltage fuses are for circuits carrying voltages greater than 38,000 VAC.
“E”Rated fuses are considered to be general purpose fuses and can be used to protect against low and high values of fault current.“R”rated fuses are designed for back-up pro-tection.They must be used in series with other devices, such as motor overload relays, in order to achieve both overload and short circuit protection.
Medium voltage fuses are not intended to provide overload protection in the same sense as fuses rated 600 volts or less.Medium voltage fuse current ratings do not have the same meanings as the ampere ratings of low voltage fuses.All medium voltage fuses are limited in their ability to inter-rupt low value overcurrents, especially those between 100%and 200% of the fuse’s continuous current rating.They are designed to carry their rated current without exceeding the temperature rise permitted by NEMA and ANSI standards.Additional application data can be found in the Fuse Application section of the POWR-GARD Products catalog (PF101).
Current limiting “E”and “R”rated fuses are equipped with a mechanical indicator or striker pin that protrudes through the fuse cap upon operation of the fuse.This provides visual identification of a blown fuse and can be used as a trigger for external devices.

Potential T ransformer (PT) fuses are current limiting fuses with high interrupting ratings designed for the protection of potential transformers.
Application Note:
When applying fuses for the protection of transformers, the magnetizing current inrush must be considered.The characteristics of the inrush, which can be matched with a fuse ’s time-current curve, should be available from the transformer manufacturer.
